Feasibility of a Home Exercise Program With the Addition of a Corticosteroid Injection in Patients With Lateral Hip Pain

We have developed an exercise protocol that we plan to evaluate in a future randomized controlled trial in combination with a corticosteroid injection. In accordance with the MRC Framework of Complex Interventions, which reccomends stepwise development of interventions and testing of feasibility before applying them to a trial, we aim to evaluate the feasibility of our intervention before initiating further trials. The purpose of this non-randomized feasibility study is to test the feasibility and acceptability of this exercise protocol with addition of a corticosteroid injection with no aim of evaluating effects. All participants in this study will receive the following interventions: * An ultrasound-guided corticosteroid injection superficial to the insertion of the gluteus medius and minimus tendons on the greater trochanter of the hip. * A home exercise program including 3 exercises, scalable to 3 different difficulty levels. * A patient information leaflet containing relevant information on managing lateral hip pain.
